An invoice is just a clean record of what you did and what you are owed. It does not need to be fancy. It needs to be clear.

A simple invoice should include:

• your name or work name
• the client’s name
• the date
• a short description of the work
• the amount due
• the due date
• the payment method

Why does this matter? Because when payment gets delayed, the person who can show the clearest record usually has the strongest position. It also helps you avoid your own confusion when you have more than one client.

Keep a simple work log too. That can be a notes file or spreadsheet showing:

• client name
• job
• date started
• date delivered
• amount agreed
• amount paid
• how paid

A quick example: you send a design draft on Monday, revisions on Wednesday, and final files on Friday. Two weeks later the client says they never got the final version and questions the price. If you have the invoice, dated message trail, and file-delivery records, the conversation becomes much simpler.

This is also protection if a job turns into a fraud problem. FTC advice on job scams makes the same broader point: records help when you need to dispute, reverse, or report something later.

What to do:

• Send an invoice as soon as the work is delivered, or by the agreed schedule.
• Keep a basic payment log for every client.
• Save delivery proof, not just the final files.
